Product Description:

The product PMB33F-10101-01 refers to the PMB Brushless Servomotors. It is developed by Pacific Scientific a manufacturer of industrial automation components. This servomotor is designed for precision control in dynamic motion applications. Under heavy-duty cycles, it produces a peak maximum torque of 12.5 Nm.

The PMB33F-10101-01 Brushless Servomotors has a maximum operating torque that reaches up to 12.4 Nm. For stable operation, the constant standstill torque is rated at 5.3 Nm. For long-term operation, the constant rated torque is 3.75 Nm. Under rated circumstances, it can operate at 4800 rpm. The maximum speed under no load is 5600 rpm. The continuous stall current is maintained at 9 A and the current required at peak torque is rated at 21.2 A. The servomotor features a round shaft design for simplified mechanical coupling. The moment of inertia is measured at 0.408 x 10^-3 kgm^2. The brushless servomotor has an inductance between lines that is rated at 2.4 mH. This confirms optimal magnetic performance during high-speed operation. The frame is typical NEMA size 34. The shaft construction and frame size allow for easy integration into compact setups. The operating temperature range is from 0 to +40 degrees Celsius. This allows the motor to perform reliably in industrial environments.

The PMB33F-10101-01 Brushless Servomotors has a humidity tolerance that reaches up to 80%, non-condensing. This improves motor durability in moisture-prone settings. The allowed installation height is specified at 1000 MSL. This confirms effective and efficient motor operation at standard altitude levels. The PMB33F-10101-01 PMB Brushless Servomotors provide reliable motion control with stable output torque. This motor combines speed, torque and electrical efficiency for high-performance automation systems.

Frequently Asked Questions about PMB33F-10101-01:

Q: How does the 2.4 mH inductance of the PMB33F-10101-01 benefit performance?

A: The 2.4 mH inductance helps minimize current ripple, enhancing smooth torque output during high-speed rotation and dynamic loads.

Q: How does the 0.408 x 10^-3 kgm² moment of inertia impact system dynamics?

A: The low moment of inertia allows rapid acceleration and deceleration, crucial for applications requiring fast positional changes and tight feedback loops.

Q: What advantage does the NEMA 34 frame offer in the PMB33F-10101-01 servomotor?

A: The NEMA 34 frame ensures mechanical standardization and simplifies retrofitting into existing systems with compact mounting dimensions.

Q: Why is a peak current of 21.2 A important in the PMB33F-10101-01?

A: The high peak current enables the motor to deliver short bursts of torque under heavy load, essential for overcoming startup or shock loads.

Q: What is the role of 9 A continuous stall current in this servomotor?

A: The 9 A rating supports consistent magnetic field strength, allowing stable torque output during extended holding or low-speed applications.
